HDTP's name is a bit deceptive - it's not doing the world textures - but rather refurbishing the original models with higher definition models and textures. This just replaces the world textures so yes, this is compatible with it.

The final result will be a sharper and more detailed visual experience, and when coupled with mods such as the High Definition Texture Project and Deus Ex : Reborn, the combined visual effect will propel Deus Ex forward into a further generation of gaming.

Rebirth was only a project to redo the SS2 AI models. SHTUP is the project to upgrade the SS2 object textures. Sadly, increasing the resolution of SS2 world (brush) textures is almost impossible, because the texture scale information is embedded in the map files.
